Control and Status
Register – ACSR
1477K–AVR–08/10
The Analog Comparator compares the input values on the positive pin PA6 (AIN0) and negative
pin PA7 (AIN1). When the voltage on the positive pin PA6 (AIN0) is higher than the voltage on
the negative pin PA7 (AIN1), the Analog Comparator Output, ACO is set (one). The compara-
tor’s output can trigger a separate interrupt, exclusive to the Analog Comparator. The user can
select Interrupt triggering on comparator output rise, fall or toggle. A block diagram of the com-
parator and its surrounding logic is shown in the Figure 50.

• Bit 7 – ACD: Analog Comparator Disable
When this bit is set(one), the power to the Analog Comparator is switched off. This bit can be set
at any time to turn off the Analog Comparator. When changing the ACD bit, the Analog Compar-
ator Interrupt must be disabled by clearing the ACIE bit in ACSR. Otherwise an interrupt can
occur when the bit is changed.
• Bit 6 – ACBG: Analog Comparator Bandgap Select
When this bit is set (one), it selects internal bandgap reference voltage (1.18V) as the positive
comparator input.
• Bit 5 – ACO: Analog Comparator Output
ACO is directly connected to the comparator output.
